seed

问题 Using an arima.sim() function to simulate time series data that follows a particular ARIMA model requires a lot of trials of this nature: library(forecast) set.seed(1) ar1 <- arima.sim(n = 10, model=list(ar=0.2, order = c(1, 0, 0)), sd = 1) ar2 <- auto.arima(ar1, ic ="aicc") ar2 One needs to be changing the seed integer until the desired result is archived. I now think of instead of changing the seed integer manually and checking with auto.arima() function I should automate the seeds with a

问题 (forgive me - I'm new to both StackOverflow & SQL) Tl;dr - When using @@identity (or any other option such as scope_identity or output variable), is it possible to also use a view? Here is an example of a stored procedure using @@identity : --SNIP-- DECLARE @AID INT DECLARE @BID INT INSERT INTO dbo.A (oct1) VALUES (@oct1) SELECT @AID = @@IDENTITY; INSERT INTO dbo.B (duo1) VALUES (@duo2) SELECT @BID = @@IDENTITY INSERT INTO dbo.tblAB (AID, BID) VALUES (@AID, @BID) GO Longer: When inserting

问题 I'ved been developing in Django and was wondering if there is a way to seed data into the database in Django. In ruby on rails, I use seed.rb and then run "rake db:seed" in command line. Main reason I want to seed some data on statuses, types, etc for the project initialization. Is there something similar ? 回答1: Similar to Rails, we also have option to seed the database. It is done using management commands. In one of your apps, use the following folder structure <project>/<app>/management
